I have attempted to provide information that will help to prevent failures that occur during partial denture construction as a result of unsatisfactory fabrication of crowns. Methods of exposure of the preparation margins, provision of adequate bulk of the elastic impression material, proper selection of die construction, and the removable die technique were discussed.
我试图提供一些信息，以帮助预防由于牙冠制作不令人满意而在局部义齿制作过程中出现的失败情况。文中讨论了预备边缘暴露的方法、弹性印模材料的足够厚度的提供、模型制作的正确选择以及可摘模型技术。
